The standard model for the analysis of variance is over-parameterized. The resulting identifiability problem is typically solved by placing linear constraints on the parameters. In the case of the ...

Liu and Senturia (1977) proved that the MINQUE of variance components in the general mixed analysis of variance can be computed in O(n) time, with n the number of observations. This can be proved in a ...

Facilities that focus on manufacturing and production track two kinds of costs: fixed costs and variable costs. The variable costs are those that change when production levels change: raw materials, ...

Both variance and sensitivity analyses provide useful information to managers of small companies as they seek to increase company performance and reduce the company's risks. While both forms of ...

Inter-individual differences in a local measure of brain structure — for example, cortical thickness — often co-vary with inter-individual differences in the structure of other brain regions.

Many finance teams treat variance analysis as a box-checking exercise: Set a threshold, flag the swing, move on. That’s why so many controllers spend days chasing noise while risks slip through. It’s ...
